    Global warming and forests: An overview of current information | real questions and Pass4sure dumps

    Unasylva - No. 163 - Forestry and environment - Global warming and forests: An overview of current knowledge

    Previous Page Table of Contents Next Page

    K. Andrasko

    Kenneth Andrasko is senior forestry analyst for the United States Environmental Protection Agency in Washington, D.C., and a US delegate to the Intergovernmental Panel on Climate Change of the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO).

    This article summarizes what the forest and climate research and policy communities currently know and sequel not know - about global warming, its potential effects on forests, and viable measures within the forestry sector to mitigate global warming. It is based on a paper prepared for an FAO Expert Consultation on climate change and forests, held in Rome from 5 to 7 March 1990.

    The mediocre temperature of the earth's surface, currently 15°C, is kept relatively constant by naturally occurring radiative or "greenhouse" gases present in the atmosphere. Most of the short wavelength radiation in sunlight passes through these gases and warms the earth's surface. Long-wave thermal radiation is then emitted by the earth and heats the atmosphere. In turn, the atmosphere re-emits long-wave radiation outwards to space and downwards to further heat the earth's surface.

    Greenhouse gases (abbreviated here as GHGs) comprehend water vapour (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), nitrogen oxides NOx), stratospheric ozone (O3, the high-altitude ozone derived from fossil fuel combustion, as opposed to the tropospheric ozone near the ground that causes smog), carbon monoxide (CO), and chlorofluorocarbons (CFC).

    The burning of fossil fuel is the leading source of greenhouse gases

    Descriptions of greenhouse gases

    Water vapour (H2O). Water vapour is the most abundant and significant infrared absorbing gas in the atmosphere, and the major constituent of clouds. Clouds play a censorious though uncertain role in the common circulation models used to simulate atmospheric-surface interactions and the greenhouse effect.

    Carbon dioxide (CO2) is by far the most abundant greenhouse gas other than water vapour. Over 90 percent of the carbon lost from conversion of forest to other land uses is released to the atmosphere as CO2, immediately through burning, and over time through rot of dead vegetation in the soil.

    Methane (CH4). Major sources of methane are anaerobic decomposition in biological systems, including rice paddies, cattle and other livestock whose digestive systems | depend on enteric fermentation, termites I (present in huge quantities in tropical forest systems, especially on disturbed sites), biomass burning, landfills and wetlands. Forest fires emit one unit of CH4 for every 100 units of CO2.

    Nitrous oxide (N2O) is a biogenic gas emitted by deforestation, biomass burning, nitrogenous fertilizers, and fossil fuel combustion. Little is known about the N2O cycle, current N2O fluxes, and processes and rates of release of N2O from soils in natural and altered ecosystems, I and from biomass burning.

    Carbon monoxide (CO), while not considered a GHG, does influence the oxidizing capacity of the atmosphere, thereby contributing to increased concentrations of CH4 and N2O. fitful burning of savannah in Africa and other continents, as a shape of livestock pasture management to stimulate growth of nutritious grass shoots may live the largest unique source, as significant quantities of CO are emitted during incomplete combustion and smouldering rather than hot, rapid burning.

    Nitrogen oxides (NOx), sulphur dioxide (SO2), ozone (O3) and chlorofluorocarbons (e.g. CFC-11 and CFC-12) derive from non-biotic, industrial anthropogenic sources (fossil fuel burning and chemical manufacturing) and are not considered here.

    Sources of greenhouse gases

    Greenhouse gases are produced both by natural phenomena and through human actions. Major natural sources of greenhouse gases related to forest ecosystems comprehend wetlands (CH4), wild ruminants and miniature herbivores (CH4), termites (CH4), wildfires (CO2, CH4, N2O, NOx, CO) and natural land ecosystems including forests, savannah and pastures (N2O). Natural emissions of greenhouse gases gain been relatively in balance for thousands of years.

    The activities of people, on the other hand, are causing significant increases in the emissions of greenhouse gases into the atmosphere. Major human-made sources of greenhouse gas emissions comprehend the burning of fossil fuels (CO2), deforestation (:mostly by burning) to invent land available for agriculture and grazing (CO2), and the burning of wood and charcoal for fuel (CO2). An estimated 5600-6000 million tonnes - 6 gigatonnes (Gt) were released into the atmosphere in 1988 in the shape of CO2 from anthropogenic (human-made) sources. The industrialized countries contributed about 75 percent of this release, and the developing countries about 25 percent The measurement record for atmospheric concentration of CO2 shows observed increases of 25 percent over the historical period.

    Scientists gain suggested for more than 100 years, and increasingly during the past decade, that these increasing emissions may strike the atmosphere's radiative balance (i.e. the percentage of the sun's radiation allowed to pass through the earth's atmosphere directly from the sun or reflected from the earth's surface), leading to a significant and long-term expand in the earth's mediocre temperature.

    circa 6 percent

    Note: 1 Pg (pentagram) = 109 tonnes

    1 Tg (teragram) = 106 tonnes

    Residence times and global warming potential of gases

    GHGs vary greatly, both in their lively residence time in the atmosphere before they are decomposed and furthermore in their radiative forcing relative to CO2, the benchmark gas. In order to compare gases, the concept of relative Global Warming Potential has emerged as a means of accounting for the varying residence times and radiative forcing potency of gases (IPCC drudgery Group 1, 1990).

    The table presents rugged estimates of annual emissions of GHGs and their contribution to greenhouse forcing in the 1980s. accent is given to the contribution from tropical forest conversion, which accounts for about 25-33 percent of total current CO2 emissions, 35 percent of CH4, and perhaps 25-30 percent of N2O.

    Some 17 million ho of tropical forest are cleared annually, almost exclusively by burning

    Greenhouse gas emissions from different forest ecosystems

    Overall, forest ecosystems store 20 to 100 times more carbon per unit district than croplands and play a censorious role in reducing ambient CO2 levels, by sequestering atmospheric carbon in the growth of woody biomass through the process of photosynthesis. However, uncertainties soundless exist with regard to carbon storage in forest cover and emissions associated with changes in or removal of forest cover for various land uses. For example, emissions of greenhouse gases from cropping practices in swidden (i.e. shifting, or slash-and-burn cycle) agriculture gain not been quantified. Neither sequel they gain reliable estimates of biomass, carbon content, and track gas emissions in a truly representative sample of natural and disturbed tropical forests and carbon fluxes in disturbed tropical soils (which may account for one-third of carbon flux from deforestation).

    Boreal forest. Recent investigations of boreal (northern largely coniferous) forest in North America hint that the carbon content and biomass estimates commonly utilized in calculations of global carbon cycle fluxes may live seriously flawed. Botkin and Simpson (1990) estimated North American boreal forest biomass carbon content at about 9700 million tonnes only a portion of previous estimates of 13800-40000 million tonnes of carbon used routinely to balance the global carbon budget.

    Temperate forest. Forests in temperate regions are now essentially in balance in terms of carbon cycling, with annual incremental growth rates roughly equal to timber harvest and deforestation for urban growth and other land uses. However, it is noteworthy that historically they gain contributed heavily to global carbon emissions, as forests were cleared (and burnt) in Europe and North America to lucid land for agricultural production.

    Tropical forest. According to Brown (1988), tropical moist forest averages about 155160 tonnes of carbon per hectare (t C/ha) of standing biomass in Latin America and Asia and ranges up to 187 t C/ha in Africa. dry tropical forest averages 27 t C/ha in Latin America and Asia and 63 t C/ha in Africa. Some 17 million hectares of tropical forest are estimated by FAO to live cleared annually, almost exclusively by burning.

    Most studies of viable climate-induced perturbations of forests gain used yardstick atmospheric common Circulation Models (GCMs) of global climate. These highly intricate three-dimensional models of atmospheric, oceanic and terrestrial interactions call global climate change (variations in regional temperature and moisture) under a scenario of doubled atmospheric concentrations of CO2 (abbreviated as 2xCO2). Their generalized predictions vary widely, and gain from increases in global hint temperature of 2.85.2°C increases of 7.1-15.8 percent in precipitation.

    Major uncertainties of several orders of magnitude exist in modelling feedbacks in GCMs. GCMs currently only crudely model ocean circulation, clouds, snow and ice coverage, water vapour, and biogeochemical feedbacks. Furthermore, poor spatial resolution of the current GCMs severely limits their ability to forecast reliably the effects of climate change on specific forests. Nonetheless, on the basis of the GCMs, viable climate responses to large increases in greenhouse gas concentrations (doubled CO2 or its equivalent in other gases) are summarized below. The qualifiers in parentheses exercise the following scale: very probable = greater than 90 percent probability; probable = greater than 67 percent probability; uncertain = hypothesized effect, with Little observational data or appropriate modelling.

    Global - hint surface warming (very probable): Scientific consensus remains, despite recent studies and press reports stressing less projected warming (see opposing view by Windelius, p. 15), that by the middle of the next century surface warming is likely to occur in the gain 1.54.5°C, for a 2xCO2 scenario.

    Global - hint precipitation expand (very probable): Increased heating of the surface will lead to increased evaporation and, as a result, to greater global hint precipitation. However, some individual regions may suffer decreases in rainfall.

    Global - mount in hint sea-level (probable): Thermal expansion of water associated with surface and oceanic warming is predicted. Rate and extent of melting of glacial and continental ice are far less certain. Predictions of changes in hint sea-level remain uncertain and difficult.

    Northern high-latitude precipitation expand (probable): elevated latitudes are expected to suffer increased poleward penetration of warm, moist air, leading to increased annual precipitation and river runoff.

    Decreases in summer soil moisture in mid-latitude interior regions are anticipated by several global warming models

    Summer continental dryness/warming (probable): A significant decrease in soil moisture for some mid-latitude interior continental regions in summer is anticipated by several models. This results from earlier snow deliquesce and earlier than daily spring and summer reductions of soil moisture.

    Regional vegetation changes(uncertain): Long-term changes in surface vegetation cover are considered an inevitable outcome of the potential climate changes reviewed above. However, major uncertainties remain about the patterns, scale, rate and feedbacks (e.g. changes in surface albedo or reflectivity, and in precipitation) of vegetative changes.

    Tropical storm increases (uncertain): Increased frequency and intensity of tropical storms, such as hurricanes (which play a major role in gap-phase dynamics in Caribbean forests, for example), may live associated with trends toward warmer, wetter climate, according to several studies.

    It is noteworthy that Little drudgery has been done thus far on applying GCM results to the tropics. Most modellers contend that climate changes are likely to live miniature in the tropics. However, comparison of model results shows that temperature ranges of 2.5-6.0°C are postulated for Southeast Asia and West Africa, and significant seasonal variations in rainfall are foreseen for West Africa (Andrasko, 1990a).

    Studies on the potential repercussion of changes in temperature and precipitation in a scenario of doubled CO2 hint a wide gain of effects both on forests and on individual trees (e.g. Shands and Hoffman, 1987; Smith conclude Tirpak, 1989; Meo, 1987).

    Potential effects of rapid warming on temperate forest ecosystems (North America and elsewhere)


    · Southern ranges of many eastern United States forest species and boreal forest in Canada and Scandinavia may shift northward 200-1000 km.

    · Northern ranges of eastern North American Species could shift up to 700 km northward, although actual migration could live as low as 100 km, owing to problems with seed dispersal and survival.

    · Forest health and survival in the long term may depend on how hastily climate stabilizes, and weather large scale-forest declines result from pests, stress from air pollution, fires, and drought.

    · Forest composition (predominance of species) may change significantly, as species less water-dependent and in the northern-part of their gain watch to become dominant.


    · Productivity declines of 46-100 percent, birth 30-80 years from the present, could result along the southern edges of species ranges, depending on levels of soil moisture.

    · Boreal forests in Scandinavia may respond very favourable to heightened temperatures and moisture and help productivity and biomass (AFOS, 1990).

    · Boreal forests and hardy gods-boreal transition areas in Canada and elsewhere may, however, decline if moisture and temperature rate changes are too hastily and nutrients are limited.


    · Increased stand decline and tree mortality are likely from insect pest population and tree disease responses to raised temperature and moisture.

    · Natural regeneration changes are uncertain and difficult to predict, hut may live enhanced for some species and provenances in Scandinavia (AFOS, 1990), and for species that exercise both seed and vegetative propagation methods for reproduction.

    · Fire incidence and damage to forests generally will live more severe, especially in stands and in vegetative zones (e.g. semi-arid tropics) becoming drier and warmer.

    This hypothesis of climate change effects on forest ecosystems has been summarized by Botkin and Nisbet (1990):

    Recent research suggests that global warning will gain ascetic and rapid effects on forest over wide areas, every bit of other factors being equal... Projections hint that effects might live so noteworthy that forest production and species composition will change over large regions, and forests in many regions may live no longer sustainable. Such responses would lead to major impacts on commercial forestry, timber supply, recreation and wildlife that depend on forest habitats, as well as water supply and erosion rates.

    Sedjo and Solomon (1989), structure on the drudgery by Emanuel et al. (1985) using the Holdridge Life Zone classification, forecast a forest life zone district decrease of 6 percent, a loss of 444 million ha of forest. Boreal forest declined 37 percent in district and lost 60.4 Gt in biomass, while tropical forests increased 28 percent in district and 57.8 Gt in biomass. Total global forest and non-forest were expected to decline 14.1 Gt in carbon overall under 2xCO2.

    Potential effects on forms gain and composition

    Boreal forest. Growth may live enhanced for boreal forests in Scandinavia (AFOS, 1990), although significant shifts in northern and southern ranges and in species composition may occur. However, Solomon, at IIASA's Biosphere Project, suggests that up to 40 percent of current boreal forest would no longer champion boreal species under 2xCO2. Very rapid warming might succumb conditions changing too rapidly for replacement species to invade from the south and boreal species to migrate northwards. Seedlings capable of survival in the conditions at the time of planting might not live able to gain maturity before conditions changed, awl seedlings capable of survival later might not survive today.

    Wheaton et al. (1987) concluded that the southern boundary of the Canadian boreal forest zone is likely to bound north 250-900 km, while the northern boundary would shift only 80-700 km, indicating a loss of district of boreal forest. Harrington (1987) suggests that, since pioneer species foster only 100-150 km a century et the northern edge of the boreal forest, the southern margin is likely to live replaced by grassland (steppe).

    Temperate forests. An overview of potential effects of doubled CO2 on selected forest systems and species in temperate North America and elsewhere is presented below in the box.

    Tropical and subtropical forests (humid and dry). Apparently no effects studies gain been performed for tropical forests. Solomon and Leemans (in IIASA, 1989) gain extended the Holdridge Life Zone vegetation mapping globally, though They conclude that areas in the tropics where existing vegetation is unlikely to survive in a warmed world comprehend northern and central Amazonia, northwestern South America West Africa' dry forest in Ethiopia and Somalia, southern Philippines, Indonesia, Sarawak, Papua New Guinea and northern Australia.

    An expand of 12 percent in total forested district in tropical ecosystems under 2xCO2 has been forecast by Emanuel et al. (1985) largely as a result of increases in precipitation in marginal sites, with increases in district of tropical wet, moist and especially tropical dry forest, and declines in district of subtropical dank and especially subtropical moist.

    Panich (1989) offers an overview of potential impacts on forestry in Southeast Asia, focusing on Thailand, by reviewing common GCM results. He notes Salati's finding that indicates that about 50 percent of the rainfall in tropical forest in Amazonia results from the forest's own transpiration; thus, declines in precipitation under climate change might greatly alter precipitation and hydrologic regimes in tropical forests. This might expand fire danger and inhibit recovery of forests after logging or natural disturbance. The impacts of altered seasonal distribution patterns of rainfall (even if the total amounts change little) might comprehend retard of the growing season, increased flooding in the rainy season, an elongated dry season, changes in cyclone numbers and intensity, and increased vulnerability of coastal forests.

    Speculation about the effects of climate change on 4.5 million km2 of mesic savannah vegetation in semi-arid tropical areas is offered by Mabbutt (1989). Latitudinal shifts of about 200 km in current boundaries of climate zones are suggested. Two competing scenarios are explored: enhanced precipitation in the tropical latitudes, but reduced rainfall in the semiarid tropics, due to diminished soil-moisture availability, versus a contrasting scenario of 10-20 percent increases in semi-arid district rainfall.

    Potential effects of climate change on tree growth and yield

    The implications of CO2 enrichment on tree growth and succumb remain unclear. Harrington (1987) summarizes current information by quoting the conclusions of Occhel and Strain with respect to perennial plants, that "increases may live accumulated from year to year and carbon may live sequestered in larger plants. However, in ecologically balanced ecosystems with animals feeding on plants, disease organisms operating, and plants competing for light, water, and nutrients, it is uncertain whether ecosystem production will increase".

    Laboratory studies of the effects of elevated CO2 levels on plants gain documented increased rates of photosynthesis, lowered plant water exercise requirements, increased carbon sequestering and increased soil microbial activity fixing nitrogen for fertilizer, thereby stimulating growth (Hardy and Havelka, 1975; Drake et al., 1988). Therefore, CO2 increases could theoretically provide significant benefits for plants and trees undergoing water stress in drier climates.

    However, very Little drudgery has been done in situ on forest or other natural communities over extended time frames (Drake e! al., 1988). The net sequel of CO2 enrichment combined with forest decline from climate change and air pollution remains uncertain. Sedjo and Solomon (1989) conclude that " the phenomenon of CO2 fertilization has not been detected in trees, despite extensive searches for it in the field... and in growth chambers".

    Secondary effects

    One of the few confident predictions about the sequel of global warming is that wildland fire activity will significantly respond to regional climate change and that the magnitude of the response will live roughly proportional (within a factor of 2) to the magnitude of the change'' (Main, 1987).

    Raised temperatures may succumb more generations a year of some insects, since they gain elevated reproductivity potential, making them likely to adapt and evolve at least an order of magnitude more quickly than the c. 30- 100-year life cycle of forest tree species serving as their hosts (Hedden, 1987). In the semi-arid tropics, changes in rainfall and the location of the savannah zone could alter locust invasion patterns in West and East Africa and the semi-arid zone in the Indian subcontinent, with deleterious effects on vegetation (Mabbutt, 1989).

    Mitigation measures or technical control options involving forestry gain been widely proposed to sequester carbon through the growth of woody plants and the behind loss of forested areas (especially in the tropics) and to reduce anthropogenic production of GHGs from forest and agricultural land exercise practices. The implementation of forestry response options lonely is, in general, not likely to stabilize atmospheric concentrations of greenhouse gases or balance countries' total CO2 emissions budgets (AFOS, 1990). Nonetheless, every bit of options for reduction of atmospheric CO2, including those involving the forestry sector, should live given complete consideration.

    Major forestry sector mitigation strategies


    · Substitute sustainable agricultural technologies for slash-and-burn deforestation.

    · Reduce the frequency and amount of forest and savannah consumed by biomass burning to create or maintain pasture and grassland.

    · decrease consumption of forest for cash crops and progress projects, through environmental planning and management.

    · help the efficiency of biomass (fuelwood) combustion in cookstoves and industrial uses.

    · decrease the production of disposable forest products by substituting durable wood or other goods, and by recycling wood products.


    · Conserve standing primary and old-growth forests as stocks of biomass

    · interpose natural forest management systems utilizing sustainable harvesting methods to supersede destructive logging.

    · Substitute extractive reserves producing timber and non-timber products sustainably, through integrated resource management and progress schemes

    · expand harvest efficiency in forests, by harvesting more species with methods that damage fewer standing trees and utilize a higher percentage of total biomass.

    · Expand fuelwood plantations to provide energy and reduce pressure on natural forests.


    · help forest productivity on existing forests, through management and biotechnology.

    · Establish plantations on surplus cropland in industrialized temperate zones and abandoned lands in the tropics.

    · Restore degraded forest and savannah ecosystems through natural regeneration and reforestation.

    · expand soil carbon storage by leaving slash after harvest and expanding agroforestry.

    Forestry sector mitigation strategies can live grouped into three classes: those that reduce sources of greenhouse gases; those that maintain existing sinks of greenhouse gases; and those that expand sinks of greenhouse gases (Andrasko, 1990b).

    Regardless of which of the three groups they topple into, every bit of strategies should to the extent feasible live ecologically sustainable overtime; capable of addressing the direct and circuitous causes of forest loss by providing an equivalent spectrum of forest products and jobs comparable to current forest exercise patterns; economically viable, preferably with low start-up costs; socially integrative, structure on local needs and traditions; technologically simple; and relatively adaptable to changing economic, political, social, ecological and climatic conditions. Before any strategy or combination of strategies is adopted on a wide scale, however, to accurately determine their relative benefits convincing net GHG balance analyses will live necessary, incorporating consideration of every bit of fluxes of multiple gases associated with every bit of phases of growth, harvest, and final disposition of biomass and carbon.

    A number of potential options to address climate change in the forestry sector are set out in the box and in the accompanying short article by Kyrklund. More circumstantial descriptions materialize in Andrasko (1990a).

    The concept of the greenhouse sequel has been widely if not universally accepted. However, because of the still-crude capabilities of current global circulation models to model intricate terrestrial-ocean-atmospheric interactions, debate remains about how much future climates are likely to warm, and when.

    International political interest is birth to focus on the exigency to identify appropriate options for forest sector policy response to potential climate change. The final report of the forestry subgroup of the Intergovernmental Panel on Climate Change (IPCC) of UNEP and WMO, a science assessment and policy process begun in 1988, has recommended early negotiations on a Global Forestry Protocol to address climate change, along with a broader energy protocol (AFOS, 1990). Policy and programmatic responses to climate change are already under artery by FAO and other local, national and international progress organizations.

    To date, most of the considerable research into potential effects of and responses to climate change on forests has taken region in North America, Europe and Australia. Investigations into potential effects on tropical forests are only now beginning.

    The threat of climate change confronts the forestry sector in every bit of regions and at every bit of levels with both biophysical and policy challenges of a far larger scale, longer time-frame, and shorter policy decision-making horizon than other recent forest sector concerns.

    Enzyme-Replacement Therapy in Mucopolysaccharidosis I | real questions and Pass4sure dumps

    All patients received weekly infusions of recombinant human α-L-iduronidase for 52 weeks. The hint activity of α-L-iduronidase in leukocytes was 0.04 U per milligram before treatment and 4.98 U per milligram, or 15 percent of normal, an mediocre of seven days after an infusion of α-L-iduronidase (i.e., immediately before the next infusion). Enzyme activity was not detectable in brushings of buccal mucosa before treatment, but seven days after an infusion, it reached a smooth of 1 percent of normal.

    Five patients (Patients 1, 4, 5, 6, and 7) had fleeting urticaria on the trunk, face, arms, and legs during an infusion given during week 4 or later, and in four patients (Patients 1, 5, 6, and 7) it recurred during subsequent infusions birth at or after week 20. During these episodes, urticaria began midway through an infusion but resolved soon after the infusion was completed. In the four patients with recurrent urticaria, the episodes eventually became less frequent and less ascetic and finally stopped. In three patients (Patients 1, 5, and 6), the urticaria was accompanied by angioedema (thickening of the tongue and tightening of the throat) on a total of nine occasions and by qualify fleeting hypoxemia on three occasions. Patient 8 had one episode of facial swelling without urticaria during the infusion at week 47. These symptoms usually resolved about one hour after the infusion was stopped. In patients with recurrent urticaria, the rate of enzyme infusion was decreased or the dose temporarily reduced, and they were given increased medications such as diphenhydramine before, and in some cases during, an infusion.

    Four patients (Patients 2, 7, 8, and 9) had biochemical evidence of complement activation during infusions given at weeks 6 and 12, as evidenced by decreased serum total complement activity (i.e., decreased CH100) and decreased C3 or C4 concentrations after infusions. Although these patients were usually asymptomatic, Patient 8 had fever, chills, and “fussy behavior” on three occasions. By week 26, there was no complement activation during infusion in any patient. In the four patients who had fleeting complement activation, serum α-L-iduronidase antibodies were detected by week 8, but the antibody levels subsequently declined or became undetectable. The antibodies did not immunoprecipitate indigenous enzyme and did not inhibit enzyme activity in vitro (Anand VA, Kakkis ED: unpublished data), nor did they alter efficacy in vivo on the basis of urinary glycosaminoglycan excretion. In every bit of 10 patients IgG antibodies developed to Chinese-hamster-ovary cell proteins that were present as a track impurity in the enzyme preparation, but clinically primary adverse events were not correlated with the presence or titer of these antibodies. There were no abnormalities in blood counts, serum chemical values, or urinalysis during treatment. Other mucopolysaccharidosis-related complications during treatment consisted of cervical subluxation requiring cervical fusion, mitral-valve replacement with coronary bypass grafting, repeated lumbar fusion, and a ventriculoperitoneal shunt, each in one patient.

    Reduction in Lysosomal Storage Figure 1. Figure 1. Changes in Liver Size in Patients with Mucopolysaccharidosis I during α-l-Iduronidase Therapy.

    Liver size was measured in terms of volume and expressed as the percentage of carcass weight, given a density of 1 g per milliliter of tissue. Patient 9 had an episode of hepatitis at 26 weeks that was believed to live due to a concomitantly taken medication and that resolved by week 30. This episode was thought to account for the fleeting expand in the size of her liver. The upper bounds of the 95 percent self-confidence interval of daily values (i.e., within the daily gain for age, as adapted from the data of Stocker and Dehner23) are 3.5 percent for boys 5 to 12 years of age, 3.2 percent for girls 5 to 12 years of age, 2.2 percent for boys 13 to 17 years of age, 2.7 percent for girls 13 to 17 years of age, 2.6 percent for men 18 years of age or older, and 2.9 percent for women 18 years of age or older.

    Liver volume decreased by 19 to 37 percent from base line in nine patients and by 5 percent in one patient at 52 weeks; the hint decrease was 25 percent (P<0.001). By 26 weeks, the size of the liver was daily for carcass weight and age in eight patients (Figure 1). In the two patients (Patients 6 and 9) who had the largest liver size relative to carcass weight at base line, the size of the liver was nigh to daily at 52 weeks (3.2 and 3.3 percent of carcass weight, respectively).

    In eight patients the size of the spleen decreased by 13 to 42 percent from base line. The hint decrease was 20 percent among every bit of 10 patients (P<0.001).

    Urinary glycosaminoglycan excretion declined rapidly after 3 to 4 weeks of treatment, and by 8 to 12 weeks it was 60 to 80 percent below the base-line values. At 52 weeks, the hint reduction was 63 percent (range, 53 to 74 percent; P<0.001). The excess urinary glycosaminoglycan excretion (that above the upper restrict of the daily value for age) was reduced by a hint of 80 percent in these patients. The results were confirmed by an assay of uronic acids and N-sulfate (a test specific for heparan sulfate). Electrophoretic studies of urine revealed a significant reduction in the excretion of heparan sulfate and dermatan sulfate, but the excretion of dermatan sulfate was soundless greater than daily in every bit of patients.

    Clinical Studies Increases in Height and Weight Table 2. Table 2. Height and Weight of Six Prepubertal Patients before Enzyme-Replacement Therapy and after One Year of Therapy.

    The height increased by a hint of 6.0 cm (5 percent) in the six prepubertal patients, and their hint rate of growth in height increased from 2.80 cm per year to 5.17 cm per year during treatment (P=0.01) (Table 2). For every bit of 10 patients, carcass weight increased by a hint of 3.2 kg (9 percent), and the hint expand was 4.2 kg (17 percent) among the 6 prepubertal patients. In these six patients, the hint rate of growth in weight increased from 1.66 kg per year before treatment to 3.83 kg per year during treatment (P=0.04) (Table 2).

    Range of Motion Figure 2. Figure 2. hint Changes in the Restriction of gain of Motion of Shoulder Flexion (Panel A), Elbow Extension (Panel B), and Knee Extension (Panel C) in Patients with Mucopolysaccharidosis I during α-l-Iduronidase Therapy.

    The hint degrees of restriction in the gain of motion of right- and left-shoulder flexion are not shown for two patients, because shoulder flexion was not evaluated in these two patients at base line. The values limn the dissimilarity between the daily maximal gain of motion for age and the measured value.

    Restriction of shoulder flexion decreased during treatment in six of the eight patients in whom it was evaluated at base line. The hint decrease in joint restriction was 28 degrees in the right shoulder (P< 0.001) and 26 degrees in the left shoulder (P=0.002) (Figure 2A). Among every bit of 10 patients, the degree of restriction of elbow extension decreased by a hint of 7.0 degrees in the right elbow (P=0.03) and 7.0 degrees in the left elbow (P=0.007) (Figure 2B). The degree of restriction of knee extension decreased by a hint of 3.2 degrees on the right (P=0.10) and 3.0 degrees on the left (P=0.09) in the 10 patients (Figure 2C).

    Analysis in individual patients revealed that the joints with the greatest degree of restriction before treatment had the greatest improvement. For example, at base line, Patients 5, 9, and 10 could not flex their shoulders beyond 100 degrees, and the gain of motion increased by 21 to 51 degrees after treatment. The improvements in the gain of motion were accompanied by patient-reported increases in physical activities, such as being able to wash their hair, hold a hamburger normally, hang from monkey bars, and play sports better.

    Airway Function

    Seven of the 10 patients had apnea, and these 7 had a decrease in the number of episodes of apnea and hypopnea during treatment, from 155 per night to 60 per night (a 61 percent decrease), with a change in the hint apnea–hypopnea index from 2.1 to 1.0 event per hour. Three of these seven (Patients 2, 6, and 9) had clinically primary sleep apnea, and in every bit of three this disorder improved during treatment. In Patient 2, the apnea–hypopnea index decreased from 4.5 events per hour at base line to 0.4 event per hour at 26 weeks, and the total length of time during sleep in which oxygen desaturation fell below 89 percent decreased from 48 minutes to 1 minute per night. At base line, Patient 6 required continuous positive airway pressure at night because of ascetic desaturation (with continuous positive airway pressure, the oxygen saturation was below 89 percent during 61 of 368 minutes of sleep). After 52 weeks of treatment, oxygen saturation was less than 89 percent for only 8 of 332 minutes of sleep, and continuous positive airway pressure was not used. Patient 9 had an apnea–hypopnea index of 9.5 events per hour before treatment and 4.0 events per hour after 26 weeks of treatment. In Patient 8, the initial apnea–hypopnea index of 0.1 event per hour increased to 3.1 events per hour at 26 weeks and to 9.3 events per hour at 52 weeks for reasons that were unclear. Eight of 10 patients or their families reported that their breathing had improved, and 5 of 7 reported quieter nighttime breathing, an improved property of sleep, and decreased daytime somnolence.

    Cardiac Function Figure 3. Figure 3. Changes in New York Heart Association (NYHA) Functional Class in Patients with Mucopolysaccharidosis I during α-l-Iduronidase Therapy.

    The changes in scores were based on information obtained from serial interviews with the patients. New York Heart Association class I indicates no symptoms with ordinary activity; class II, symptoms with ordinary activity and a slight limitation of activity; class III, symptoms with less-than-ordinary activity and marked limitation of activity; and class IV, symptoms with any sort of activity or at rest. The dissimilarity between pretreatment scores and scores at 52 weeks was significant (P=0.002).

    The New York Heart Association functional classification was determined by serial interviews with the patients. every bit of 10 patients reported an improvement by one or two classes (Figure 3), but there was no objective data from echocardiographic studies to verify direct cardiac benefit. The improved functional scores may reflect improvements in aspects of the disease other than cardiac function. When base-line echocardiograms were compared with those obtained after 52 weeks of treatment, tricuspid regurgitation or pulmonic regurgitation was decreased in four patients, but mitral regurgitation worsened in two patients (Patients 2 and 7). At base line, Patient 6 had atrial flitter and clinical signs of cardiac failure, including dyspnea at ease and pitting edema. After 12 weeks of treatment, he had sinus meter with first-degree obstruct and his dyspnea at ease and pitting edema had resolved.

    Symptomatic Changes

    Before treatment, every bit of 10 patients reported a lack of endurance and limitations in their ability to accomplish daily activities, but exercise tolerance was not formally tested. During treatment, every bit of patients had improved endurance and fewer limitations in their ability to accomplish daily activities, and after 26 weeks of treatment, many were able to walk farther, run, and play sports. Patients 3, 4, and 5 reported the resolution of severe, incapacitating headaches after 6 to 12 weeks of treatment.

    Ophthalmic Changes

    The extent of corneal clouding did not change in any of the eight patients with this problem. Several patients reported decreased photophobia or conjunctival irritation. Visual acuity improved from 20/1000 to 20/200 (in one eye) in one patient and slightly in two others.
